ALAN K. GILLESPIE, OF ST. LOUIS, MISSOURI, ASSIGNOB. TO BRECHT COMPANY,OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI.

REFRIGERATOR.

To all whom it may concern!- I Be it known that I, ALAN K. Grnnssrm, acitizen of the United States of America, residing at the city of St.Louis, State of Missouri, United States of America have invented a cortain new and useful ltefrigerator, of which the following is such a full,clear, and exact description as will enable any one skilled in the artto which it appertains to make and use the same, reference being bad tothe accompanying drawings, forming part of this specification.

My invention relates to an improvement in counter refrigerators, and itsobjects are to provide an arrangement in which the refrigerating meansis situated below a display chamber in connection wi 111 ns formaintaining a suitably low in rature throughout the display chamber; toprovide an eflicient and novel form of ice chamber; and to so arrangeall the parts as to form a refrigerator having storage and displaychambers in which the display chamber will be of convenient height. andeasy of access. Other objects and advantages of my invention 'willappear from the following more detailed description. I

In the accompanying drawings, Figure l is a front elevational view of arefrigerator constructed in accordance with my invention; Fig. 2 is aview partly in plan and part1 in horizontal section along line 2-2 ofFig. 1; Fig. 3 is a vertical transverse cross section along line 3-3 ofFig. 1'; and Fig. t is a perspective view of the ice chamber.

The refrigerator is provided with the usual suitably insulated walls,and comprises a display chamber 1, a storage chamber 2 and ice chambers3, spaced apart and situated between the display chamber and the storagechamber. The ice chambers communicate with a common ice hopper xi,closed by a plurality of doors 5. This hopper is provided with aninclined interior surface 6, as shown in Fig. 3, which facilitates theforcing of ice from the hopper into the ice chambers 3.

The display chamber is provided with doors 7, partly of glass, and thefront wall of this chamber is formed of a plurality of spaced glassplates 8. 6* I The ice chambers 3 terminate shprt 9f the front wall ofthe refrigerator, and an insulating member 9 passing lengthwise ofSpecification of Letters Patent.

,frigcrator cooperating "also results in an even the refrigerator andacross the ends of the ice chambers forms, with the front wall of therefrigerator, an air passage 10, connecting the storage chamber 2 withthe display chamber 1. A glass ballle plate 11 extends I Patented Jan.8,1918.' Application filed October 26, 1916. Serial No. 127,764.

lengthwise of the display chamber and from the insulating member 9 to apoint near the top of the chamber and forms, with the front wall 8, acontinuation of the air pas sage 10.

A drain pipe or pipes 12 are provided for the ice chambers and areplaced in any suit able position. Articles to be kept cool are placed inthe storage chamber 2 through a door 13, or if they are to be displayed,into the chamber 1 through a door 7.

the operation of the refrigerator the an is brought to its lowesttemperature while between and adjacent to the ice chamzers The warmestair will of course be at djacent to the walls of the chambers, andparticularly in the passage 10. The condition just dcscri ed leads tothe circulation of air from the displaychamber downward between thevarious ice chambers and upward to the display chamber through thepassage 10. This circulation will be continuously maintained, becausethe temperature of the air is always reduced, while passing between theice chambers 3, to a point below that of the air in other parts of thechamber, and this heavier air moves downwardly,displacing and forcingthrough the passage 10 the lighter air underneath it.

It will be noted that with the form of ice chambers I employ, a verylarge area of with the result that I may use a smaller quantity of saltin the ice chambers, or I can reducethe temperature in the refrigeratorto a point lower than would be ossible if a smaller area of cooling surace were provided. The spacing of the ice chambers throughout the lengthof the re with the baffle 11, distribution of cooled {lair throughoutall parts of the display cham- Having fully described my invention, whatI claim as new and desire to secure by Letters Patent of the UnitedStates is:

1. A refrigerator comprising an upper display chamber, a plurality ofcontainers for cooling means located beneath said chamber and spacedapart to provide a plullt) rality of fines for the egress ofair from thedisplay chamber.

2. A refrigerator comprising an upper display chamber, a lower chamber,a plurality of containers for cooling means located beneath said upperchamber and spaced apart to provide a plurality of flues for thedownward passage of air from the upper to the lower chamber, and a fluefor the upward passage of air from the lower to the upper chamber.

3. A refrigerator comprising a lower stora e chamber, an upper displaychamber, a plurality of inclosed ice containers between said chambersand spaced apart to provide a plurality of passages between them fromthe upper to the lower chamber, and means forming a passage for thereturn of air from the lower to the u per chamber, said means comprisinga mail extending to the upper part of the display chamber.

4. A refrigerator comprising an upper display chamber having atransparent front wall, a lower storage chamber, co tainers for coolingmeans located betwee said chambers and spaced apart to providd pastainers, said air passages communicating with therefrigerating chamberand spaced over one wall of said chamber.

6. In a counter refrigerator, the combination of an upper displaychamber, a lower storage chamber, a plurality of inclosed ice containerslocated between said chambers and spaced apart, said containersextending to a point back of the display chamber, and

.an ice hopper communicating with the rear portions of said chambers.

In testimony whereof, I have hereunto set my hand andafiixed my seal.
